Irish showjumper Denis Lynch has made a last-minute appeal to the Court of Arbitration for Sport (CAS) to try to get back on the Irish Olympic team.

And CAS said it will rule on his case tomorrow (28 July).

Mr Lynch and Billy Twomey were chosen as the individual riders to represent Ireland in the showjumping competition at Greenwich (4-8 August).

But after his horse, Lantinus 3, failed a hypersensitivity test at Aachen (5-6 July) and was disqualified, Horse Sport Ireland announced they would be looking for a replacement.

And Cian O’Connor was called up in his place.

Now Denis has launched an appeal to CAS which will be heard by a special Olympic sitting of the court in London.

Denis’ brother and manager Shay Lynch told the Irish Examiner that Denis felt he had “a reasonable chance of success”.
